CAUTION!
Mixing of coolants other than specified HOAT en-
gine coolants, may result in engine damage and may
decrease corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.
Do not use plain water alone or alcohol base engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to 5 Years or 100,000 miles before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
coolant throughout the life of your vehicle. Please review
these recommendations for using Hybrid Organic Addi-
tive Technology (HOAT) coolant.
When adding coolant, a minimum solution of 50% rec-
ommended Mopar Antifreeze/ Coolant 5 Year/100,000
Mile Formula HOAT (Hybrid Organic Additive Technol-
ogy), or equivalent, in water should be used. Use higher
concentrations (not to exceed 70%) if temperatures below
234ÉF (237ÉC ) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.

WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.
Brake Hoses
Inspection should be performed whenever the brake
system is serviced or at intervals specified. Inspect hy-
draulic brake hoses for surface cracking, scuffing or worn
spots. If there is any evidence of cracking, scuffing, or
worn spots, the hose should be replaced immediately!
Eventual deterioration of the hose can take place with
possible burst failure.
Clutch Hydraulic System
The clutch hydraulic system is a sealed maintenance-free
system. In the event of leakage or other malfunction, the
system must be replaced.
Clutch Linkage
If the clutch pedal linkage begins to squeak or grunt, the
clutch pedal pivot bushings should be lubricated. Refer
to Fluids, Lubricants and Genuine Parts for the correct
lubricant type.

Transfer Case
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
Front Drive Shaft
The front drive shaft contains a grease fitting which
should be serviced at every oil change (see maintenance
schedule A/B).
Manual Transmission
Fluid Level Check
This fluid level can be checked by removing the filler
plug. If the level of the lubricant is more than 1/4º (6.4
mm) below the bottom of the filler hole while the vehicleis on level ground, enough lubricant should be added to
bring the level to the bottom of the filler hole.
Lubricant Selection G56 (6 ± Speed Manual
Transmission Ð If Equipped)
This transmission does not require periodic changing. If
it becomes necessary to add or change the fluid in this
transmission, refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
Automatic Transmission
Fluid Level Check
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. Operation of the trans-
mission with an improper fluid level will greatly reduce
the life of the transmission and of the fluid. Check the
fluid level whenever the vehicle is serviced.
412 MAINTAINING YOUR VEHICLE

Automatic Transmission Fluid and Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center.
It is important that proper lubricant is used in the
transmission. Refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
The fluid and filter(s) should be changed as specified in
the Maintenance Schedule (Section 8).
NOTE:If the transmission is disassembled for any
reason, the fluid and filter(s) should be changed.
Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. Exception to
this policy is the use of special dyes to aid in detectingfluid leaks. The use of transmission sealers should be
avoided, since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
ªpurgeº excess grease and the bearing will look slightly
wet. This is normal. Periodic inspection for excess play is
recommended.
Rear Wheel Bearings Ð Manufacturer's Axles
These bearings are normally considered permanently
lubricated. Cleaning and repacking is required only
when axle shafts are removed or in case of extreme water
or dust contamination.

Selection of Lubricating Grease
The National Lubricating Grease Institute (NLGI) has
developed a symbol (Certification Mark) to aid the
vehicle owner in the proper selection of grease for the
lubrication of wheel bearings and chassis components.
This symbol (an example is shown below) is located on
the grease container and identifies the application and
quality of the grease.
There are two groups
identified, those for wheel
bearings (Letter ªGº) and
those for chassis (Letter
ªLº) lubrication. Perfor-
mance categories within
these groups result in dual
letter designations for
each group. The letter des-
ignations shown in the ex-
ample are the highestquality level available and when combined as shown can
be used for both wheel bearing and chassis lubrication.
Use only those greases that have the NLGI symbol on the
container along with the proper quality level for your
application.
Noise Control System Required Maintenance &
Warranty
All vehicles built over 10,000 lbs (4 535 kg) Gross Vehicle
Weight Rating and manufactured for sale and use in the
United States are required to comply with the Federal
Government's Exterior Noise Regulations. These vehicles
416 MAINTAINING YOUR VEHICLE

can be identified by the Noise Emission Control Label
located in the operator's compartment.Required Maintenance for Noise Control Systems
The following maintenance services must be performed
every 6 months or 6,000 miles (9 600 km), whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed
or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and the cover is tight. Check all hoses leading to the
cleaner for tightness. The gasket between the air cleaner
housing and throttle body must be intact and in good
condition. The engine air cleaner filter must also be clean
and serviced according to the instructions outlined in the
appropriate maintenance schedule.
